I(Straight M35) and my wife(Bi F35) have been married for 15years in a mostly monogamous relationship. (We went on a few dates with guys before covid, but then haven't since). I've realised over the last few years that I just felt like our relationship might feel more "right" if there were other people involved. It's a really difficult feeling to describe, because I wouldn't say I feel like it would be "better", and it doesn't feel like it's currently "wrong". It might sound stupid, but it's like I yearn for my wife to be dating someone else, as well as myself. Did/does anyone else get this feeling? I don't think my wife understands this, like it's just a sexual thing that will pass. I'm worried that if it keeps getting stronger it will affect our relationship. Any advice on how to communicate this effectively?
